Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484454, here are decompositions:

5 + 31484449 = 31484454
37 + 31484417 = 31484454
41 + 31484413 = 31484454
101 + 31484353 = 31484454
137 + 31484317 = 31484454
151 + 31484303 = 31484454
173 + 31484281 = 31484454
251 + 31484203 = 31484454

Showing the first eight; more decompositions exist.
